Description

Technical Field

[0001] The invention relates to the technical field of oncology, in particular to a respiratory rehabilitation training device for lung cancer patients. Background Art

[0002] Lung cancer is one of the malignant tumors with the fastest growing incidence and mortality rates and the greatest threat to human health and life. The incidence and mortality rates of lung cancer in men rank first among all malignant tumors, while the incidence and mortality rates in women rank second. The cause of lung cancer is still not fully understood. A large amount of data shows that long-term heavy smoking is closely related to the occurrence of lung cancer. Existing studies have shown that the probability of long-term heavy smokers developing lung cancer is 10-20 times that of non-smokers. The younger the age at which people start smoking, the higher the chance of developing lung cancer. In addition, smoking not only directly affects one's own physical health, but also has adverse effects on the health of people around them, leading to a significant increase in the incidence of lung cancer in passive smokers. The incidence of lung cancer in urban residents is higher than that in rural areas. This may be related to urban air pollution and carcinogens contained in smoke. Therefore, non-smoking should be advocated and urban environmental sanitation work should be strengthened.

[0003] A Chinese patent discloses a respiratory training breathing device for respiratory medicine with a publication number of CN215025782U, with an application date of 2021.03.17. The patented technology cooperates with an installation ring, a sliding groove, a limit block, a rotating block, a threaded rod, an equipment spring, an equipment top plate and an equipment vertical rod. The installation ring is rotated at this time. The installation ring will drive the rotating block and the equipment spring to move upward, and the distance between the equipment top plate and the rotating block will be shortened, so that the equipment spring is compressed, and the distance between the equipment top plate and the installation ring is changed, so that the initial elastic coefficient of the equipment spring is changed, so that the training intensity can be increased and decreased according to patients with different recovery degrees, so as to make it more convenient for staff to use and increase applicability. However, when the above patent is used, the user's exhalation and inhalation are collected by the same air bag, so the exhaled gas will be repeatedly inhaled, and the oxygen content of the gas will decrease after being exhaled, which is not conducive to the patient repeatedly performing the breathing exercises provided by the device.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the respiratory rehabilitation training device for lung cancer patients, the patient holds a respirator, puts his mouth close to the inside of the breathing circle, and then inhales through his mouth. The external airflow enters the patient's mouth through the bottom display tube, the air inlet pipe, the branch pipe, and the connecting pipe. When the patient exhales, the gas is discharged through the connecting pipe, the branch pipe, the air outlet pipe, and the top display pipe. Through the design of two one-way valves, the gas intake has different pipes to avoid the simultaneous intake and exhaust of a single pipe, so that the exhaust gas is inhaled by the intake air again before it is completely discharged from the pipe, thereby preventing the patient from exhaling the exhaust gas in the pipe during breathing exercises.

[0015] In addition, in the respiratory rehabilitation training device for lung cancer patients, when the external airflow contacts the bottom rotating blades, due to the airtightness of the outer periphery of the outlet pipe and the inlet pipe, the airflow contacts the inclined surface of the rotating blades, which will push the rotating blades to rotate. According to Bernoulli's principle and Newton's third law, the rotating rotating blades push the air downward to form a strong wind, so that the air will give the rotating blades and the rotating pieces an upward reaction force, causing the rotating pieces to rotate and move upward along the surface of the threaded rod. If the patient's suction is strong enough, the speed of the external air flowing in will be faster, and then the speed of the rotating blades rotating and the speed of the upward propulsion will also be faster. If the moving rotating piece can contact the corresponding touch generator, then the touch generator will send a signal to the alarm, and the alarm will generate an alarm signal to remind the patient that the inhalation exercise has met the requirements.

[0025] like Figure 1 As shown, a respiratory rehabilitation training device for lung cancer patients includes a rear cylinder 10 and a front cylinder 11. The front cylinder 11 is completely consistent with the rear cylinder 10, and the rear cylinder 10 is turned forward 180 degrees to be aligned with the front cylinder 11.

[0026] refer to Figure 1, a pair of positioning holes 12 are provided on the front top of the rear cylinder 10, and the two positioning holes 12 are located at the corners of the rear cylinder 10; a pair of plug blocks 13 are fixedly connected to the bottom of the front side of the rear cylinder 10, and the two plug blocks 13 are also located at the corners of the rear cylinder 10. Since the front cylinder 11 is the reversed rear cylinder 10, the position of the plug block 13 on the rear cylinder 10 corresponds to the position of the positioning holes 12 on the front cylinder 11, and the position of the positioning holes 12 on the rear cylinder 10 corresponds to the position of the plug block 13 on the front cylinder 11. When in use, the front cylinder 11 and the rear cylinder 10 are spliced ​​together, so that the corresponding plug block 13 is inserted into the corresponding positioning hole 12. The spliced ​​front cylinder 11 and the rear cylinder 10 form a breathing cylinder 20. Since the breathing cylinder 20 is spliced ​​in design, it is convenient to disassemble and clean.

[0027] Preferably, a group of hand-holding grooves 91 are provided on the left side of the front side of the respirator 20. The hand-holding grooves 91 are ergonomically designed to fit the fingers. The hand-holding grooves 91 can facilitate the patient to hold the surface of the hand-holding grooves 91 when using the respirator 20.

[0028] refer to Figure 1 , a first placement groove 30 is provided in the middle position on the right side of the rear cylinder 10; a second placement groove 31 is provided on the top and bottom of the rear cylinder 10, and the first placement groove 30 and the second placement groove 31 are semicircular. A breathing ring 32 is installed inside the first placement groove 30, and the breathing ring 32 is funnel-shaped and made of rubber. The left and right sides of the surface of the breathing ring 32 are respectively fixedly connected with fixing rings 33. When in use, the opposite sides of the two fixing rings 33 are inserted into the inside of the first placement groove 30, so as to achieve the connection between the breathing ring 32 and the rear cylinder 10, and at the same time, the breathing ring 32 can be effectively prevented from shaking back and forth. When in use, the user aligns the mouth with the breathing ring 32, and the face fits the breathing ring 32 to prevent air leakage, and then exhales or inhales into the breathing ring 32.

[0029] refer to Figure 1 , 2The left side of the breathing circle 32 is fixedly connected to the connecting pipe 34, the left side of the connecting pipe 34 is fixedly connected to a branch pipe 35, the top of the branch pipe 35 is fixedly connected to an outlet pipe 40, the connection between the branch pipe 35 and the outlet pipe 40 is provided with a first one-way valve 42, the first one-way valve 42 only allows the inlet pipe 41 to exhaust air to the outlet pipe 40; the bottom of the branch pipe 35 is fixedly connected to the inlet pipe 41, the connection between the branch pipe 35 and the inlet pipe 41 is provided with a second one-way valve 43, the second one-way valve 43 only allows air to enter the connecting pipe 34 from the inlet pipe 41. Through the design of two one-way valves, the gas intake has different pipelines, avoiding the single pipeline from working for intake and exhaust at the same time, so that the exhaust gas is not completely discharged from the pipeline and is sucked into the intake air again, thereby preventing the patient from exhaling the waste gas in the pipeline during breathing exercises.

[0030] refer to Figure 1 , 2 A pair of clamping rings 44 are fixedly connected to the outer side of the top of the air outlet pipe 40; the same pair of clamping rings 44 are fixedly connected to the outer side of the bottom of the air inlet pipe 41. When in use, the opposite sides of the pair of clamping rings 44 are inserted into the second placement groove 31 to fix the air outlet pipe 40 and the air inlet pipe 41. When the front cylinder 11 and the rear cylinder 10 are combined, the air outlet pipe 40, the air inlet pipe 41 and the breathing ring 32 can be fixed inside the breathing cylinder 20, thereby achieving the installation of the device, so as to facilitate the subsequent disassembly of the device.

[0031] refer to Figure 2 , 3 A dustproof net 50 is provided inside the connection between the two display tubes 45 and the air outlet pipe 40 or the air inlet pipe 41. The dustproof net 50 is used to prevent the patient from inhaling external dust into the lungs when using the device for breathing training, thereby causing coughing.

[0032] refer to Figure 3 , 47. The two dust screens 50 are fixedly connected to the opposite sides with threaded rods 51, and the outer sides of the two threaded rods 51 are fixedly connected with blocks 52. The bottom of the threaded rods 51 is threadedly connected with a rotating piece 53. A group of rotating blades 54 are fixedly connected to the outer surface of the rotating piece 53. The rotating blades 54 are designed to be arc-shaped with the surface gradually rising from left to right (similar to the shape of a wing). When the rotating blades 54 have an upward gas flow, due to the airtightness of the outer periphery of the outlet pipe 40 and the inlet pipe 41, the air flow contacts the inclined surface of the rotating blades 54, which will push the rotating blades 54 to rotate. According to Bernoulli's principle and Newton's third law, the rotating rotating blades 54 push the air downward to form a strong wind. The air will give the rotating blades 54 and the rotating piece 53 an upward reaction force, so that the rotating piece 53 rotates along the surface of the threaded rod 51 and moves upward. Since the magnitude of the downward reaction force is closely related to the inclination angle of the rotating blades 54 (the larger the inclination angle, the greater the lift), the inclination angle is slightly larger here.

[0033] Preferably, a touch generator 55 is installed on the left side of the interior of the air inlet pipe 41, and a similar touch generator 55 is installed on the left side of the interior of the air outlet pipe 40. An alarm 90 is installed on the left side of the interior of the rear cylinder 10, and the alarm 90 is electrically connected to the two touch generators 55. When in use, the patient holds the respirator 20, puts his mouth close to the inside of the breathing circle 32, and then inhales through his mouth. The external airflow enters the patient's mouth through the bottom display tube 45, the air inlet pipe 41, the branch pipe 35, and the connecting pipe 34. When the external airflow contacts the bottom rotating blade 54, due to the airtightness of the outer periphery of the air outlet pipe 40 and the air inlet pipe 41, the airflow contacts the inclined surface of the rotating blade 54, which pushes the rotating blade 54 to rotate. According to Bernoulli's principle and Newton's third law, the rotating rotating blade 54 pushes the air downward to form A strong wind and air will give the rotating blade 54 and the rotating piece 53 an upward reaction force, so that the rotating piece 53 rotates along the surface of the threaded rod 51 and moves upward. If the patient's suction force is strong enough, the speed of the external air flowing in will be faster, and then the speed of the rotating blade 54 rotating and the speed of the upward propulsion will also be faster. If the moving rotating piece 53 can contact the corresponding touch generator 55, then the touch generator 55 will send a signal to the alarm 90, and the alarm 90 will send an alarm signal to remind the patient that the breathing exercise has met the requirements. Similarly, when the patient exhales, the gas is discharged through the connecting pipe 34, the branch pipe 35, the air outlet pipe 40, and the top display tube 45. When the gas contacts the top rotating piece 53, it will also make the rotating piece 53 and the rotating blade 54 rotate and move upward. If the rotating piece 53 contacts the corresponding touch generator 55, then the touch generator 55 will send a signal to the alarm 90, and the alarm 90 will send an alarm signal to remind the patient that the breathing exercise has met the requirements. When performing exhalation exercise, there is no airflow flowing into the air inlet pipe 41, so the rotating piece 53 and the rotating blade 54 lose their rotational force, and due to their own gravity, they reverse and fall back to the bottom of the threaded rod 51. Similarly, when performing inhalation exercise, there is no airflow flowing into the air outlet pipe 40, so the rotating piece 53 and the rotating blade 54 also reverse and fall back to the bottom of the threaded rod 51 due to gravity. This makes it convenient for patients to perform multiple sets of breathing exercises.

[0034] Since the above-mentioned breathing exercise has no way to adjust the intensity of breathing, it cannot meet the breathing exercise needs of patients at different stages, so an adjustment mechanism 60 is proposed.

[0035] refer to Figure 3 , 47. The adjustment mechanism 60 includes a movable groove 601 on the right side surface of the display tube 45, and a movable rod 602 that can move up and down is installed inside the movable groove 601. A ring 603 is fixedly connected to the left side of the movable rod 602. The ring 603 is arranged on the outside of the threaded rod 51 and does not contact the threaded rod 51. The bottom of the ring 603 is fixedly connected to a downward pressure spring 604, and the bottom of the downward pressure spring 604 is fixedly connected to a pressure ring 605, and the pressure ring 605 is also arranged on the outside of the threaded rod 51. When the rotating piece 53 moves upward during inhalation, it will gradually contact the pressing ring 605 until the rotating piece 53 contacts the surface of the pressing ring 605. If the rotating piece 53 has enough airflow support, it will drive the pressing ring 605 to move upward before contacting the touch generator 55. For the rising rotating piece 53, the pressing ring 605 provides an upward resistance for the rotating piece 53, so that the alarm signal of the operation completion will be triggered only when the patient has a strong suction force. Since the resistance of the pressing ring 605 is provided by the downward pressing spring 604, and the downward pressure of the downward pressing spring 604 is proportional to the degree of deformation, the lower the pressing ring 605 is, the earlier it will contact the rotating piece 53, so that the degree of compression of the downward pressing spring 604 to trigger the touch generator 55 is greater, and the suction force required by the patient is greater. Thus, the effect of adjusting the intensity of the patient's breathing exercise is achieved. At the same time, when the suction stops, the pressing spring 604 drives the pressing ring 605 to move downward, and the pressing ring 605 presses down the surface of the rotating piece 53, so that the rotating piece 53 reverses faster and falls into the bottom of the threaded rod 51 faster. Similarly, it is the same when the patient exhales.

[0036] Specifically, refer to Figure 5 , 6 8. A positioning mechanism 70 is provided on the outer side of the movable groove 601, and the positioning mechanism 70 includes a pair of positioning blocks 701. The movable groove 601 is located in the middle of the positioning block 701. A sliding groove 702 is provided on the opposite side of the positioning block 701. A sliding plate 703 is slidably connected to the opposite sides of the two sliding grooves 702. The rear side of the sliding plate 703 is fixedly connected to the movable rod 602. A group of positioning grooves 704 is provided on the surface of the sliding plate 703. A rotating rod 705 is rotatably connected to the front end of the opposite side of the two positioning blocks 701. A flip plate 706 is fixedly connected to the surface of the rotating rod 705. A fixed point block 707 is fixedly connected to the rear side of the bottom of the flip plate 706.

[0037] Preferably, the surface of the sliding plate 703 is in contact with the surface of the display tube 45, and the area of ​​the sliding plate 703 is large enough to cover the movable groove 601 whether sliding down or moving up, thereby preventing gas from leaking from the movable groove 601 during use.

[0038] When in use, the nurse can adjust the breathing intensity of the device according to the patients at different stages. When in use, if the intensity of breathing exercise is to be increased, the sliding plate 703 is slid downward, and the sliding plate 703 drives the moving rod 602 to rotate, and the moving rod 602 drives the pressing spring 604 and the pressing ring 605 to move downward. When the appropriate intensity is selected, the flip plate 706 is flipped downward, and the fixed point block 707 is inserted into the corresponding positioning groove 704 to complete the fixing of the sliding plate 703 and the moving rod 602. At the same time, since the airflow speed caused by the patient's exhalation and inhalation is different, the two adjustment mechanisms 60 at the bottom and top can be adjusted separately according to the conditions of different patients.

[0039] The working principle of the present invention is as follows: when in use, the patient holds the respirator 20, puts the mouth against the inside of the breathing circle 32, and then inhales through the mouth. The external airflow enters the patient's mouth through the bottom display tube 45, the air inlet tube 41, the branch tube 35, and the connecting tube 34. When the external airflow contacts the bottom rotating blade 54, due to the airtightness of the outer periphery of the air outlet tube 40 and the air inlet tube 41, the airflow contacts the inclined surface of the rotating blade 54, which will push the rotating blade 54 to rotate. According to Bernoulli's principle and Newton's third law, the rotating rotating blade 54 pushes downward. The air forms a strong wind, and the air will give the rotating blades 54 and the rotating sheet 53 an upward reaction force, so that the rotating sheet 53 rotates along the surface of the threaded rod 51 and moves upward. If the patient's suction is strong enough, the speed of the outside air flowing in will be faster, and then the speed of the rotating blade 54 rotating and the speed of the upward propulsion will also be faster. If the moving rotating sheet 53 can contact the corresponding touch generator 55, then the touch generator 55 sends a signal to the alarm 90, and the alarm 90 sends an alarm signal to remind the patient that the inhalation exercise has met the requirements.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
